To my eye the regex reads better if you start the memory group with a set of digits (thus removing the worry about leading spaces) and then follow with grouped spaces and digits with a quantifier of 0 to 19. That avoids the adjacent \s* tokens which might be a little confusing at first glance. Also, you don't need the parentheses around the match.
I hope this is of interest. Cheers, JohnGG In reply to Re^2: printing 20 characters in a line.
